Within Kagoshima Prefecture, the lands that hold no coastline at all can be counted on one hand. Soo is one of them. In the northern interior of the Osumi Peninsula, where a basin opens to the north and tablelands and hills spread, it is not fishing but field crops and cattle that have supported the living. The head count of beef cattle was, at the time of the merger, among the leading in the prefecture. Moreover, the former town on the eastern side is deeply bound, in living and culture, to a city of the neighboring prefecture across the prefectural border. Three towns were bound into one and a city was born, and thereafter it has lost population — Soo’s numbers carry two pasts inscribed in them: a landlocked interior of stock-raising, and a living sphere that straddles a prefectural border.
In the northern interior of the Osumi Peninsula, one of the few cities in Kagoshima Prefecture that holds no coastline. In 2005, three towns of Soo County were bound into one and established. The population has decreased, from 42,287 in 2005 to 33,310 in 2020. What I (Atlas) want to follow is not the sign "a city of the prefecture’s east," but the causal thread: how the past of a three-town merger, an interior of stock-raising, and a living sphere shared with a neighboring prefecture is translated into today’s population and finances.
01 · Seeing the present Soo in its numbers
In the latest Population Census the population is about thirty-three thousand (33,310 in 2020). Because this city was established in 2005 when three towns were bound into one, the statistics cover the period after establishment. The population after establishment has decreased, from 42,287 in 2005 to 39,221 in 2010, 36,557 in 2015, and 33,310 in 2020.
Looking inside, the figure of a landlocked interior city of stock-raising raising its age appears. The share aged 65 and over rose from 32.9% in 2005 to 37.5% in 2015 and 41.4% in 2020, passing four in ten. The household-with-children share is 14.7% in 2020, and the crude birth rate is 5.0 per thousand in 2020. The Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.30 in fiscal 2023 — a level able to cover only three-tenths of expenditure with its own tax revenue, with a large degree of reliance on the local allocation tax. The figure shows in the numbers: a landlocked interior land of stock-raising, losing population while widening its city area through merger. Why it takes this form cannot be read without going back to the past of a landlocked interior landform, stock-raising, a living sphere shared with a neighboring prefecture, and the three-town merger.

02 · A landlocked interior tableland, stock-raising, a living sphere shared with a neighboring prefecture, the three-town merger — the history behind the numbers
What supports this town’s frame is the landform of a landlocked interior tableland, stock-raising, a living sphere shared with a neighboring prefecture, and the merger of three towns. The starting layer is the landlocked interior tableland. This land lies in the northern interior of the Osumi Peninsula and, among the lands of Kagoshima Prefecture, holds no coastline — one of the few such. A basin opens to the north, and tablelands and hills spread. The landlocked interior tableland was the foundation of this town.
This tableland nurtured field crops and stock-raising. Holding no sea-based livelihood, this land took field crops and, above all, the raising of beef cattle as its mainstay, and its head count was, at the time of the merger, among the leading in the prefecture. And the former town on the eastern side has been deeply bound, in living and culture, to a city of the neighboring prefecture across the border. A living sphere that crossed the prefectural line set the direction of this land’s living. The path to becoming a city, too, mirrors this town. In 2005, the three towns of Soo County were bound into one and became the present city. By this the range the city measures widened. A landlocked interior tableland nurtured stock-raising, and upon that stock-raising and a living sphere that straddles a prefectural border the three-town merger was layered — and so the present Soo’s form stands.

03 · In a landlocked interior land of stock-raising, losing population while widening the city area through merger
What characterizes Soo is that, while it holds the past of an interior of stock-raising and a living sphere shared with a neighboring prefecture, it is losing population after widening its city area through merger. From the 42,287 of 2005 after establishment to the 33,310 of 2020, some nine thousand were lost over fifteen years. Even in this land whose mainstay is field crops and cattle, the aging of the bearers of farming and stock-raising overlapped with some of the younger generation moving toward larger cities, and one can read that the town’s age as a whole rose. That the share aged 65 and over passed four in ten at 41.4% in 2020 is an expression of that.
On the other hand, the Childcare Waitlist was zero in both 2024 and 2025, the household-with-children share is 14.7% in 2020, and the crude birth rate is 5.0 per thousand in 2020. The Fiscal Capacity Index of 0.30 is a level able to cover only three-tenths of expenditure with its own tax revenue, showing the large degree of reliance on the local allocation tax seen in common across interior lands of farming and stock-raising. The landlocked interior land of stock-raising is now losing population while widening its city area through merger. Some nine thousand left over fifteen years, the elderly passed four in ten, and own tax revenue covers only three-tenths of expenditure. These three are not separate events but appear in the numbers as one continuous movement — the bearers aging, the younger generation slipping out to the cities, and the remaining industry not thickening the tax source.

04 · A town where a landlocked interior tableland nurtured stock-raising and shared a living sphere with a neighboring prefecture
In Soo, several faces of differing character overlap. One is the past of a landlocked interior tableland — in the northern interior of the Osumi Peninsula, one of the few lands in the prefecture holding no coastline. Another is the character of a land of stock-raising — holding no sea-based livelihood, it took field crops and beef-cattle raising as its mainstay and held one of the leading head counts in the prefecture at the time of the merger. And it bears the face of a living sphere shared with a neighboring prefecture — the former town on the eastern side is deeply bound, in living and culture, to a city across the border. The condition of a tableland holding no coastline drew into this land stock-raising in place of fishing, and a direction of living that straddles a prefectural border.
A landlocked interior tableland nurtured stock-raising, and shared a living sphere with the land across the prefectural border — and onto that the three-town merger was layered, and the present Soo was made. The geography of "an interior in the northern Osumi Peninsula holding no coastline" was the starting point; from there field crops and cattle raising grew, a living sphere that crossed the prefectural line was nurtured, and the city area was bound into one. In this order this town was formed.

05 · Atlas’s note — in a landlocked interior land of stock-raising, reading the gap between the borders of administration and of living
Lay out Soo’s numbers and the indicators of an interior city of stock-raising raising its age line up: a city area widened by merger, an aging rate of 41.4%, a household-with-children share of 14.7%, and a fiscal capacity of 0.30. To my (Atlas’s) eye, which cannot shake the habit of cross-checking a column of numbers one by one, what first stays with me is the fact that this town is "one of the few cities in Kagoshima Prefecture holding no coastline." Among the lands of a prefecture that faces the sea, a landlocked interior, lacking the livelihood of fishing, has specialized in the land-based livelihoods of field crops and stock-raising. The location of an interior within a coastal prefecture bred a specialization toward a land that raises cattle. This chain explains the numbers well.
Another thing I want to consider is that the eastern side of this town "shares a living sphere with a city across the prefectural border." When the living bonds are deeper with a city across the border than with a city of one’s own prefecture, the border of administration and the border of living do not coincide. The city’s population and finances are measured within the prefecture’s frame, yet the direction of people’s feet crosses the prefectural line. The line drawn by administration and the line drawn by living can fall out of step.
A landlocked interior landform bred a specialization toward a land that raises cattle, and tilted the direction of living across the prefectural border — that far is the fact that rests in my (Atlas’s) palm, and into the appraisal beyond it I do not step.
